Zoals de foto laat zien werkt het dus zonder problemen. Deze is ook geïsoleerd zodat je meerderen van deze kabels kan gebruiken op een usb hub . ### ⭐⭐⭐⭐⭐ Review *by D***M on 31 May 2024* Quand on cherche une liaison USB-ttl fiable, ce composant a une bonne puce FTDI, avec driver compatible windows même >10, linux ubuntu, mac, et il est isolé, donc plus de pb de CEM et tension secondaire disponible. Attention, il y a plusieurs versions chez le fabricant. Ca m'a sauvé pour faire fonctionner un appareil et le PC, car sinon les deux plantaient avec un câble non isolé. Je crois que ça existe aussi chez ce fabricant en version USB-UART, les signaux UART étant inversé par rapport à ttl, mais en 3 ou 5V contrairement au RS232 en -12/+12V. ## Frequently Bought Together - DSD TECH SH-U09C3 Isolated USB to TTL Adapter Featuring FTDI FT232RL IC - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - WWZMDiB Mini USB to TTL Serial Converter Adapter, 3.3V/5.5V, FTDI Breakout Board for Arduino --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/276256682-dsd-tech-sh-u09c3-isolated-usb-to-ttl-adapter-featuring](https://www.desertcart.pl/products/276256682-dsd-tech-sh-u09c3-isolated-usb-to-ttl-adapter-featuring) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-25*
